Nikon NEF RAW: recover after deletion
How can I recover deleted Nikon NEF originals after deletion?
Short answer
Yes, often, if the Nikon card has not been written since. NEF uses TIFF-based directories with Nikon metadata, previews and compressed sensor data, and a scan can recognise them after deletion. Remove the card, scan it read-only for NEF plus JPEG if you used both, and develop each file fully.
The situation
deleted Nikon NEF originals no longer appears in its recording folder even though the storage device is still detected.
Deletion removes the name, not the picture. A NEF keeps its TIFF-based directories, its Nikon metadata and its sensor data in place until the card is written again, so the practical task is to stop everything that writes and then read the card out carefully.
01 / Diagnose
Work out what actually disappeared
Erasing on the Nikon body or on a computer releases the exFAT entry and frees the clusters that held the file. The NEF structure stays intact and recognisable. Compression matters when judging results: lossless compressed frames vary in size, so a small file is not automatically a damaged one and has to be developed to be assessed.
Deletion can release a directory reference before later writes reuse every block that belonged to the file. For Nikon NEF RAW, this matters because NEF uses TIFF-based directories with Nikon metadata, previews and compressed or uncompressed sensor data.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Switch the camera off and take the card out before the next release writes a fresh frame into the freed clusters.
- 2
Note the Nikon body, the RAW compression setting and whether RAW plus JPEG was active during the shoot in question.
- 3
Scan the card read-only through a reader for NEF, and for JPEG as well when both files were recorded together.
- 4
Export the frames to another drive and develop each one in software that supports the body before reusing the card.
Do not let the camera format the card to make it usable again, and do not take a replacement frame. A single NEF occupies tens of megabytes, so one new picture can take several deleted frames with it and end the recovery before it starts.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
Frames whose clusters have been reused stay incomplete, and a damaged NEF is not repaired here. File Recovery Hero reads the Nikon card in exFAT read-only, scans free of charge and asks 50 EUR once for the export, which always goes to a different drive.
04 / Verify
Check the recovered content, not just its name
Develop every frame instead of scanning a contact sheet. A recovered NEF is sound when it opens at full sensor resolution, its metadata still names the body and the lens, and the file sizes group plausibly around the compression setting that was used.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can Nikon exFAT card be recovered in this situation?+
Deletion removes the name, not the picture. A NEF keeps its TIFF-based directories, its Nikon metadata and its sensor data in place until the card is written again, so the practical task is to stop everything that writes and then read the card out carefully. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not let the camera format the card to make it usable again, and do not take a replacement frame.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
Develop every frame instead of scanning a contact sheet.
